Professor David and others frowned.


    The other party''s procrastination is too much to pay attention to them.


    "Principal Caspar, I think we might as well go straight over. Then maybe we can find evidence. " Professor David got up.


    "Professor David, this is Stanford. I believe my students. And now, you''re talking about everything. I need to hear what my students say first. Before that, I believe my students did not commit such illegal acts. " Caspar said calmly.


    Although the tone is very relaxed, there is no doubt.


    Professor David frowned and looked at Qin Feng.


    He wants Qin Feng to collect evidence.


    But Qin Feng didn''t move at all.


    It''s no use going here.


    Don''t say you don''t know Marissa Mayer''s residence. Even if you know, you can''t get in.


    I''m not a policeman. How can I enter someone else''s house.


    Even the police, you don''t want to go in.


    Therefore, Qin Feng didn''t bother to toss.


    Tossing around for a long time is a joke.


    Therefore, Qin Feng drank the precious blue mountain coffee hard.


    One cup after another.


    It''s really delicious.


    Of course, there must be some criticism. There is no tea for coffee.


    Tea is the best drink.


    In particular, Chinese people realize that tea is healthier, while coffee contains caffeine, which is unhealthy.


    In fact, professional nutritionists have analyzed it.


    Compared with green tea and coffee of the same quality, the contents of energy, carbohydrate, phosphorus, potassium, sodium, magnesium and niacin in coffee are slightly higher than those in green tea, and the contents of protein, fat, dietary fiber, calcium, iron, zinc, vitamin C, riboflavin and thiamine are slightly lower.


    Compared from the functional components.


    The functional components of green tea are mainly polyphenols catechins.


    Catechin, also known as tea tannin and catechol, is the general name of flavanols in tea. Catechins have a variety of biological effects, such as antioxidant effect, reducing the risk of cardiovascular disease, reducing the risk of cancer and so on. Each cup of green tea contains about 2 grams of tea, and each gram of green tea contains about 59.3-103.2 mg of catechin.


    According to the reference intake of dietary nutrients for Chinese residents (2013), the antioxidant effect of catechin can be observed only when 250 mg catechin is consumed every day; Daily intake of 400 mg catechin can reduce the risk factors of cardiovascular diseases such as body weight, blood glucose, blood pressure and blood lipid, so as to reduce the risk of cardiovascular diseases; Daily intake of 600 mg catechin can reduce the risk of prostate cancer in men.


    The functional component of coffee is also polyphenol compound chlorogenic acid.


    Chlorogenic acid has antioxidant, free radical scavenging, anti-inflammatory, antibacterial, antiviral and other biological activities. Population epidemiological investigation and intervention studies and animal tests show that chlorogenic acid plays an important role in regulating sugar and lipid metabolism, improving insulin resistance, reducing the risk of type 2 diabetes and cardiovascular diseases, protecting the nerves, liver, lung, eye, joints and other organs from oxidative and inflammatory injury, and protecting DNA macromolecules.


    Every 100 ml of coffee contains about 70-350 mg of chlorogenic acid. According to the reference intake of dietary nutrients for Chinese residents (2013), the daily intake of 350-500 mg chlorogenic acid is helpful to regulate glucose and lipid metabolism.


    As for coffee, people usually think that coffee contains caffeine, which is harmful to the body for a long time. In fact, tea also contains caffeine. Each cup of green tea containing 2 grams of tea contains about 20 mg of caffeine; Each cup of coffee contains about 2 grams of coffee powder and 63 mg of caffeine. According to the European Food Safety Research Association, when adults consume less than 400 mg of caffeine a day, it will not cause harm to the body. Therefore, there is no need to worry about excessive caffeine intake when drinking tea and coffee in moderation.


    In a comprehensive comparison, green tea and coffee, as the most popular drinks in the East and the west, have different nutritional values. Long term adherence to drinking 3 cups of green tea or 2-4 cups of coffee a day is conducive to good health.


    Therefore, many things are not what people think.


    A lot of common sense is not necessarily correct.


    It''s just a fixed thought in people''s mind.


    People are the most stubborn. Is the most difficult to change some of their shortcomings.


    This is like saying that "fat house happy water" is bad for your health, but any behavior that puts aside the dose to talk about toxicity is a rogue.


    Fat house happy water, a lot of long-term drinking is really bad for your health. But the question is, how much can most people drink a day?


    Ordinary people drink one or two bottles a day (ordinary packaging), which is not harmful to their health.


    After all, fat house happy water is mainly sugar.


    Therefore, Qin Feng is also very relieved to drink this precious coffee.


    At first, Caspar didn''t notice.


    Just, unconsciously, a pot is gone. He went to grind.


    After a while, it was gone again.


    Looking at this rare can of Blue Mountain coffee beans, there are fewer and fewer, and it will soon reach the bottom, Kaspar noticed the "culprit".


    You guy, when the Blue Mountain coffee is ice water, drink it like this!


    However, I am the president of Stanford and I invited people to drink. I can''t say that I cut off the confession in advance.


    Ordinary people, then do it. But as president of Stanford, he can''t do such a thing.


    The man wants face and the tree wants skin.


    He''s really boring.


    Finally, I can only watch Qin Feng clap his round belly and enjoy the coffee burping with fragrance on his face.


    Very delicious.


    Principal Caspar gave a slap on the cheek.


    "Headmaster Caspar, why haven''t people come yet after drinking all this coffee?" "Make complaints about the wind," too. Is Stanford so slow? "


    Qin Feng was full and began to make trouble.


    Principal Caspar was furious.


    Do you have the reason to cook after dinner.


    Just after drinking his precious blue mountain coffee, he came to trouble.


    How long has it been? Less than 20 minutes.


    You just drank up a whole can of Blue Mountain coffee. You''re going too far.


    "Classmate Qin Feng, do you know how old Stanford is?" Principal Caspar gnashed his teeth.


    "Yes! I''ve been here! " Qin Feng nodded, "when I took the exam four years ago, I took a turn at Stanford. It covers an area of about 33 square kilometers, which is really large. The sixth largest university in the United States. "


    Qin Feng grinned.


    "Shall I calculate the distance and steps from here to the dormitory area?" Qin Feng asked, "I still say. How fast does the headmaster''s female secretary walk? "


    The sarcastic meaning in Qin Feng''s words jumped into the air.


    Principal Caspar frowned.


    He didn''t expect that Qin Feng was so tricky. This guy is hard to deal with.


    "Classmate Qin Feng, if you want to calculate, I''d like to hear whether you have the same talent in mathematics." Principal Caspar said faintly.


    For Qin Feng''s cunning, he naturally can''t get angry. You know, there are 12 professors at Harvard watching. If he wants to be angry, it will be a shame to spread it.
